Tuggeranong (Isabella Plains) AWS Number: 70339 just recorded minus 6.1 degrees equal to 18th May 1999.
And against the growing Canberra urban heat island UHI.
I aim to post a screen save overnight if my %@@#%ing software will do the upload. www.bom.gov.au/jsp/ncc/cdio/weatherData/av?p_nccObsCode=123&p_display_type=dailyDataFile&p_startYear=&p_c=&p_stn_num=70339

Six ALDI red or white to anybody spotting the MSM mentioning UHI in these circumstances.

  1. It looks like Casino in NSW will have its coldest mean temp for May since records started in 1908. I wonder how many sites will have their coldest May minimums on record?

  3. Would be happy for an explanation from you about lower temperatures in SE Qld.
    The SOI is normally an indicator of La Nina and El Nino whereby La Nina indicates wetter conditions and even flooding with lots of clouds which in turn should reduce temperature. El Nino is supposed to indicate drier conditions with possible drought and high temperatures due to reduced cloud.
    I have been recording daily &average monthly SOI from the long paddock site. I find that the La Nina ended in February and it appears El Nino has started this month.
    I measure rainfall daily. I find that for the last 6 months rainfall has been less than half normal. Rain fall is normally the heaviest in the first 4 months (summer). Close to where I live the average for February is a little over 260mm and the maximum has been 1819mm. This year the rainfall for the first 4 month has been 40% of average (February 97mm) . The rainfall appears more similar to a drought period as in 2000.

  4. As data is updated for end May I can try and put where we are in perspective.
    The Crohamhurst rainfall station has closed a few years back but I might be able to build a composite using some Maleny sites. Quite apart from how ludicrous it is that the super-wealthy Wide Brown Land can not maintain the “world heritage” Crohamhurst rainfall series. Hundreds of BoM rainfall records are blighted by “the Great Deterioration” of data series by gaps over the last 20 or more years. Could also be named – “the Great Dying of Rain Gauges”. I have blogged on this over years.
    You are lucky in Qld to have your DPI and their great LongPaddock www pages and those useful rainfall posters.

  5. Broome is also cold, only 1942 and 1976 was May colder at the airport, and before that, 1896 and 1940 at the old post office site a mile away. I want global warming back!
    8.5C this morning again as well as two days ago.

  6. Link below to BoM map of rainfall percentages for May.
    www.bom.gov.au/climate/maps/rainfall/?variable=rainfall&map=percent&period=month&region=nat&year=2023&month=05&day=31

    Even our GreenLeftAlboABC can not avoid the issue now – Australia’s average temperatures plummet in May as Sydney experiences coldest nights in 66 years 31May23
    www.abc.net.au/news/2023-05-31/australia-average-temperatures-plummet-in-may/102413068
    And as usual NEVER a mention that the Sydney cold is in the face of the largest urban heat island in Australia.
    Here is a link to the BoM minimum anomaly map of Australia – as I said earlier the coldest anomalies points to areas where it might be worthwhile searching data for records.
    www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&time=latest&step=0&map=minanom&period=month&area=nat
    You can also find that the coldest areas in the contouring might be areas where there are no BoM stations.

  7. Your Aldi wine prize is quite safe, Warwick – the MSM point blank refuse to allow the terminology “UHI” to darken their doorstep. It’s one of John Kerry’s aliens.

    Whenever a “colder/hotter/wetter/drier than xxxx (some date)” statement is used, I ask what was the atmospheric CO2 concentration then ? We are aware that this underlines the point that atmospheric CO2 concentrations are trivial in the climate component mix, so this thread scores a bullseye.

  8. Thanks to Andy White for his comment at my 2012 blog – “Measuring BoM headline bias when introducing their 3 month temperature Outlooks”

    Andy commented – Thanks for all your efforts in this space Warwick, but here we go again.
    Bureau of Meteorology tips warm, dry winter for virtually all of Australia
    By weather reporter Tyne Logan 1Jun23
    www.abc.net.au/news/2023-06-01/warm-dry-winter-tipped-for-virtually-all-of-australia/102399002
    Well after the monster wet last year a dry winter could surely not surprise anybody.
    Since the election of the Albanese Govt the BoM map of Twelve-monthly mean temperature anomaly for Australia (thats an average of daytine & night-time temperatures) looks to me to be saying that the wide brown land has cooled slightly over the 12 months to 31May23
    www.bom.gov.au/jsp/awap/temp/index.jsp?colour=colour&time=history%2Fnat%2F2022050120230430&step=0&map=meananom&period=12month&area=nat
    Fascinating for a Govt harming our economy with NetZero policies aimed at preventing global temperatures(measured mostly in urban heat islands) from rising.

  9. Like Andy White above – Geoff Sherrington has posted at my 2012 blog “Measuring BoM headline bias when introducing their 3 month temperature Outlooks”
    Is there a link somewhere on www pointing people to that obscure 2012 blog of mine?
    Here is Geoff’s link.

    Hi Warwick, UAH monthly released today and plotted by Monckton method:
    Cheers geoff www.geoffstuff.com/uahjun2023.jpg

  10. SOI for May -16.2 which is into the El Nino area indicating a dry period. May rainfall 109.8mm compared to 130 year average of 154.2mm. However, 3.5 mm yesterday and some rain tonight which is a good start for June (130yr average 109.1mm)

  12. Casino now officially coldest May on record as were many other sites. All states recorded below min and max monthly means except WA max mean. The Aus mean min was 7th lowest on record for May – lowest since 1944. Anything on the media?

  13. Note Chris Gillham’s updated chart at his Australia Cooling page
    www.waclimate.net/australia-cooling.html
    Australian climate cooling since 2012
    Chris charts both the BoM Australian ACORN temperatures –
    and the NASA satellite trend from UAH(University of Alabama at Huntsville)
    Great Southern Wide Brown Land voters elect the GreenLeft AlboTealsGovt who are implimenting NetZero policies aimed at preventing the rise of global temperatures.
    Said “global temperatures” being mostly measured in growing urban heat islands.
    You could not make this up.

  14. Perth is reported two days ago (June 6) as being below 10C at 1:30pm.

    “Western Power asked customers in parts of Pinjarra, Meadow Springs and Wembley Downs in the early evening to also reduce their electricity consumption” [from the West Australian]

    To avoid larger scale blackouts …
